摘要/Abstract

摘要： 立体光固化(SLA)作为碳化硅陶瓷材料3D打印的主流方法之一,具有广泛的应用前景。本文针对立体光固化成型的碳化硅素坯,进行了脱脂与反应熔渗试验,通过烧结过程中密度、强度、收缩率、微观结构的变化,研究了立体光固化成型碳化硅素坯的烧结特性。结果表明:脱脂后样品具有较低的烧结收缩率,特别是增材方向,为0.88%,脱脂后的坯体强度为0.26 MPa;光敏(UV)树脂的残留热解碳(PyC)呈网状结构连接碳化硅颗粒,热解碳局部出现断裂,同时样品沿打印层间出现微裂纹;反应熔渗后残留热解碳与硅反应生成β-SiC,连续相硅填充孔隙与层间微裂纹,样品体积密度为2.79 g/cm³,抗弯强度为183.99 MPa。

Abstract: Stereolithography (SLA), as one of the main methods of 3D printing of SiC ceramics materials, has a wide range of applications. In this paper, the experiments of debinding and reactive melt infiltration (RMI) were carried out on the SiC prepared by stereolithography. The sintering characteristics of the SiC were studied through the changes of density, strength, shrinkage,and microstructure. The results show that,the shrinkage of the sample is low after debinding, especially along the additive direction, which is only 0.88%. The strength of the sample after debinding is 0.26 MPa. The residual pyrocarbon (PyC) formed by the UV resin is connected with SiC particles in a network structure. The pyrocarbon locally breaks and microcracks appear along with the printed layers. The residual pyrocarbon reacts with silicon to form β-SiC after reactive infiltration and the silicon fills the pores and microcracks. The density of the sample is 2.79 g/cm³, and the bending strength is 183.99 MPa.

Key words: stereolithography, SiC, reactive melt infiltration, 3D printing, microstructure, mirror
